Aiding the share move, Alcoa delivered a pretty upbeat outlook for this year:

In 2013, Alcoa sees global aluminum demand growth of 7 percent, up from 6 percent in 2012 and ahead of the 6.5 percent rate required to meet the Company’s forecast of a doubling in global aluminum demand between 2010 and 2020. Aluminum demand grew 10 percent in 2011 on top of 13 percent growth in 2010.
